drm/rockchip: add PINCTRL dependency for LVDS 

The new driver fails to build when CONFIG_PINCTRL is disabled:

drivers/gpu/drm/rockchip/rockchip_lvds.c: In function 'rockchip_lvds_grf_config':
drivers/gpu/drm/rockchip/rockchip_lvds.c:229:39: error: dereferencing pointer to incomplete type 'struct dev_pin_info'
   if (lvds->pins && !IS_ERR(lvds->pins->default_state))

This adds the respective Kconfig dependency.
